Dear Lybrate User
For children maximum growth is 0 to 6 months then 6 to 12 montha. After that it is during their teens. Make her eat on her won. Whatever she finishes in 20 mi s is fine. Do not give fied food or junk food inbetween. If she is hungry gi e normal food with dhal and vegetables. She will be fine. Mark her weight on the growth chart and if your doctor is worried then only you need to worry.

You should eat heavy diet if your health permit food as much as baby can music therapy is one the best make baby busy and tired before sleep make pleasant environment around the room including his bed and other.

Get a good check up of tonsills and adenoids (if cold is regular and trouble sleep)

advice child to exercise like dance this will help as deep breath will clear nostrils and sinuses and also will help in building immune system strong.

Always be very careful with the medicine around in home with such a young child. Besides the drug itself being harmful the child can even choke on it. In case of accidents like these rinse get mouth immediately and induce her to vomit out the medicine. She should be fine here since she did not swallow it. Take care n stay alert!

As your baby is only 21 days old, you should only continue mother's milk as baby should consume mother's milk for 6 months without even giving water as there are lots of healthy nutrients and benefits in mother's milk for baby.
